  1. 1. Evaluation of the effects of four consolidants on matte paint and their ageing

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Angela Caira; [2021-09-14]
    Keywords : matte paint; consolidant; artificial ageing;

    Abstract : This research starts with the analysis of the funeral coat of arms of Pehr Stålhammar, dated 1701, as a case material of matte paint in need of consolidation. This study aims to assess the effect of four consolidants on matte paint and their ageing properties. READ MORE

  3. 2. Mechanism of Formation of Soft Particles in Biodiesel Fuel Blends

    University essay from KTH/Materialvetenskap

    Author : Roberta Maria Fiorenza; [2020]
    Keywords : ;

    Abstract : The large environmental impact related to the use of fossil fuel has driven the shift toward renewable sourced alternatives. Fossil diesel can be nowadays replaced by biodiesel, obtained from vegetable oils and fats, mostly used as biodiesel blends. READ MORE

  4. 3. Fracture strength of three-unit fixed partial denture in lithium disilicate, press versus milled, in-vitro study

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Hogir Ismail Ahmad; Noor Khazal; [2019]
    Keywords : Fracture strength; Three-unit fixed partial denture; FPD; Lithium disilicate; Conventional Manufacturing; CAD CAM; In vitro; Fracture mode;

    Abstract : Syfte: Syftet med denna studie är att jämföra fraktur styrkan och frakturmönster hos tre-leds broar utförda i litiumdisilikat när broarna tillverkas genom pressteknik jämfört med frästa tre-leds broar genom CAD/CAM system.Hypotes: Pressteknik är bättre lämpad med avseende till fraktur resistens då fräsning av litiumdisilikat block kan resultera i defekter och spänning i materialet, detta gör materialet mer benäget till chipping/mikroabrasioner på ytan som skulle kunna propagera och på så sätt påverka fraktur resistensen.

  5. 4. Model-Free Damage Detection for a Small-Scale Steel Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Aaron Ruffels; [2018]
    Keywords : damage detection; structural health monitoring; machine learning; artificial neural network; model bridge;

    Abstract : Around the world bridges are ageing. In Europe approximately two thirds of all railway bridges are over 50 years old. As these structures age, it becomes increasingly important that they are properly maintained. If damage remains undetected this can lead to premature replacement which can have major financial and environmental costs. READ MORE

  6. 5. Interdependence between seed age and aerated steam treatment intensities

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Maria Schück; [2012]
    Keywords : seed ageing; accelerated ageing; seed viability equation; aerated steam treatment; storability; commercial seed sanitation; shelf-life; Triticum aestivum L.; seed vigour;

    Abstract : Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. READ MORE
